Check-All Valve also offers FEP Encapsulated springs, which are springs, incased in heat shrinkable FEP tubing. The ends of the tubing are plugged with FEP and sealed. FEP Encapsulation may reduce flow capacity and the cracking pressure may vary. Some springs for .348 and .464 orifice diameters are not available with FEP Encapsulation. Consult the factory for a substituted spring.
Temperature range for FEP Encapsulation material is -320° F to 400° F.
